Question

How many grams of P2O5 can be produced from 4.6 x 1023 atoms of P?

Answer 1

`\\ \tt\longmapsto No\:of\:moles=(No\:of\:atoms)/(Avagadro's\:no)`

`\\ \tt\longmapsto No\:of\: moles=(4.6* 10^(23))/(6.022* 10^(23))`

`\\ \tt\longmapsto No\:of\:moles=0.76=0.8mol`

Now

`\\ \tt\longmapsto Given\:mass=No\:of\:moles(Molar\:mass)`

`\\ \tt\longmapsto Given\:mass=0.8(284)`

`\\ \tt\longmapsto Given\:mass=227.2g`
